[rancid] HP Procurve (hlogin): interaction in configure mode: possible?

[Emmanuel Halbwachs]

Hi Everybody,

I'm a newbie on this list.

I'm happily using rancid (2.3.1, the one in Debian stable etch) for
several monthes, but till now only for pushing/retrieving some info
with {c,h}login. I plan to use version control for config later.

My point:

I am trying to change some config parameters in ~50 HP Procurve with
some commands like this:

$ hlogin -v foo -e bar -c "conf t; foobar; wr mem" $switch

The output then hangs after the "conf t" command:

switch> enable
Password:
switch#
switch# no page
switch# conf t

-> hang :-(


When using hlogin without entering in configure mode, everything works
just fine.

I tried to massage the -c command with "\n" without any results.

I understand that dealing with the HP CLI seems to be a PIA (thus
hpuifilter), but is there a way to enter some commands in configure
mode?

TIA for any hint,

[john heasley]

two things; 1) your string of commands would leave cli in configuration mode,
and hlogin would run "exit;exit" then leaving it at the un-enabled cli. you
need
-c "conf t; foo; exit"
2) it appears that hlogin has difficulty with the prompt changing. A change
was applied to clogin to make this work, but apparently not applied to hlogin.
you should be able to work-around it using the -x method.

Hello,

First, thank you very much for your answer.

you need
-c "conf t; foo; exit"

Yes, you're right, it was missing in my example.

2) it appears that hlogin has difficulty with the prompt changing. A change
was applied to clogin to make this work, but apparently not applied
to hlogin. you should be able to work-around it using the -x
method.

Well, I tried this as well (I forgot to tell it) and it hangs the same
way:

***@sionet:~# cat ~eh/rancid/rancid-cmd
conf t
sh sys
exit

***@sionet:~# /usr/lib/rancid/bin/hlogin -v foo -e bar -x ~eh/rancid/rancid-cmd switch
switch
spawn hpuifilter -- telnet switch

I will try rancid 2.3.2a7 to see if it give some improvement on the
subject.

Nevertheless, I am still open to any hint with HP and configure mode
;-)

the attached patch should fix both issues; -c and -x.

Hello,

Post by john heasley
the attached patch should fix both issues; -c and -x.
# Turn off the pager and escape regex meta characters in the $prompt
send "no page\r"
- regsub -all "\[)(]" $prompt {\\&} reprompt
+ regsub -all {[)(]} $prompt {\\&} reprompt
+ regsub -all {^(.{1,11}).*([#>])$} $reprompt {\1([^#>\r\n]+)?[#>](\\([^)\\r\\n]+\\))?} reprompt
expect {
-re $reprompt {}
-re "\[\n\r]+" { exp_continue }

Works like a charm, tested with -c and -x

Thanks a lot!
